The VEO AM-204 Aluminum Monopod from Vanguard extends to 55.1" and folds down to 18.5". It has 4 sections that are locked with flip locks, and a rubber foot for stability on slippery surfaces.
A rubber cover hides the top mounting screw allowing you to use the monopod as a walking stick, with the soft rubber handle providing a comfortable grip.
It is perfect for my needs
